☆ In Super Mario Galaxy 2, Bowser uses Power Stars to stay giant. He attacks Mushroom Kingdom and flees with Princess Peach. Mario needs to follow and defeat him to complete the game. In his battle, he orbits around the planet Mario and Luigi face him on. Bowser mainly attacks by spitting out fire and punching the planet. When meteors hit the planet, they will be motionless. But when Bowser punches the planet with the meteors on it, they will be pushed into the air. Mario or Luigi must then jump onto the meteor and ground pound it into Bowser. Doing this a few times will defeat him. In the final battle, Bowser has a second phase. The background will disappear and he will be battled in an endless meteor field. Mario or Luigi must get onto the meteors and ground pound them into him before he punches the meteors. After taking enough hits he will get sucked into a vortex and Peach will be saved.
